mingmingl retitled this revision from "[LICM][AArch64] Detects that ExtractElement is not free in AArch64 when deciding whether to sink an operation in the exiting block of a loop." to "[AArch64][CostModel] Detects that ExtractElement at index is not free in AArch64 when result is used as integer.".

For `getVectorInstrCost` method, optionally pass a pointer of Instruction, and each target can retrieve the (use) context and customize cost estimation. For AArch64 implementation, fall back to use VectorInsertExtractBaseCost rather than regard extract element at index 0 as a free operation.
